摘要
以H2SO4为电解液对高纯铝箔进行阳极氧化,考察电解电压对多孔阳极氧化铝膜微观形貌的影响。结果表明,在一定范围内氧化铝膜纳米孔孔径随电解电压增加而增大,但过高的电压值将导致铝箔的快速击穿。1.0mol/L H2SO4为电解液采用20V电解电压制得的氧化铝膜最好。电解液硫酸浓度过高使得纳米孔局部连通现象增多。
The oxide aluminum membrane is prepared by anodic oxidization of high-pure aluminum foil in H2SO4 electrolyte,and the effects of electrolyte voltage on the microcosmic morphology of oxide aluminum membrane are investigated.The results show that aperture of nano-pore is increased with the increase of electrolyte voltage within the certain range.However the exorbitant electrolyte voltage is prone to rapid breakdown of aluminum foil.The optimal oxidation aluminum membrane is obtained under 20V in 1.0 mol/L H2SO4 electrolyte.The local connectivity is increased while the H2SO4 concentration in electrolyte is exorbitant.
